How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
A JSON object with a `success` boolean and a `result` object containing funding rate and derivatives data for the requested symbol (e.g. BTC, ETH, SOL). Exact fields within `result` are dynamic but reflect current funding rate conditions for the queried asset.
Example use cases
Check BTC perpetual funding rate
“Can you look up the current funding rate for BTC perps right now?”
Monitor ETH derivatives funding
“What's the funding rate for ETH-PERP at the moment? I want to know if it's worth holding my long position.”
SOL funding rate for arbitrage decision
“Pull the current funding rate for SOL so I can decide whether to go long or short on the perp.”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/derivs/funding?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need current funding rate data for major crypto derivatives (BTC, ETH, SOL) and are operating in an x402-enabled micropayment environment. It accepts both base tickers (BTC) and full symbol formats (BTC-USD, BTC-PERP), normalizing them server-side. Prefer this over manual scraping when you need a programmatic, pay-per-call approach to derivatives data.
Side effects
- Missing or invalid `symbol` query parameter returns an error
- Unrecognized ticker symbol may return empty or error result
- Payment failure (USDC x402 payment not completed) blocks access with HTTP 402
- Rate limiting or server errors may return 5xx responses
- Network timeout if the upstream derivatives data source is unavailable
